Zvishandiso
1.thyl acetate inoshandiswa seyakagadziriswa yervarish, lacquers, uye nitrocellose; sechibereko chemuchero chemuchero; Mukuchenesa zviumbwa; uye mukugadzira kweiyo yekunyepedzera silk leather, zvinonhuhwirira, uye mafoto mafirimu maficha (merck 1996). Ethyl Acetate inowanzoshandiswa seSolvent mu organic maitiro. Zvinosvibiswa zvakatipoteredza; Chikafu chinosvibisa.
2.ethyl acetate inoshandiswa zvakanyanya se solvent uye duliuent, kuve inofarirwa nekuda kwemutengo wayo wakaderera, uye kunhuhwirira kwakaderera. Semuenzaniso, zvinowanzoshandiswa kuchenesa mabhodhi ematunhu uye mune mamwe zvipikiri zvipikiri zvinopfura (aceton uye acetonitrile zvinoshandiswawo). Bhinzi yekofi uye tii mashizha anogadziriswa neiyi solvent zvakare mune pendi semutambi kana kuomesa. [Kuongorora kunodiwa] Mune zvinonhuhwirira, inobuda nekukurumidza, ichisiya kunhuhwirira kwezvinonhuwira paganda.
3 - 1 - Rabhoritari Inoshandisa
MuBabhoritari, musanganiswa une ethyl acetate zvinowanzoshandiswa muColumn chromato edzidzo uye kuwedzerwa. Ethyl Acetate haawanzo kusarudzwa seyakagadziriswa solvent nekuti inowanzoita hydrolysis uye trans estation.
3 - 2 - kuitika mumasaini
Etiral Acetate ndiyo yakajairika ester in the waini, kuve chigadzirwa cheanonyanya kujairika organic acid - acetic acid, uye iyo ethyl doro rakagadzirwa panguva yekufemerwa. Kunhuhwirira kweTevyl Acetate kwakanyanya kujeka mumasaini madiki uye kunobatsira kune iwo maonero e "chibereko" muwaini.
3 - 3 - Instological Kuuraya Mumiriri
Mumunda weIntomology, Ethyl Acetate ndeye Aspaphyxiant inoshanda yekushandisa muchidimbu kuunganidza uye kudzidza. Mukuuraya chirongo chakabhadharwa neEthyl acetate, maVapris anouraya akaunganidzwa (kazhinji munhu mukuru) nekukurumidza pasina kukuparadza. Nekuti haisi hygroscopic, ethyl acetate zvakare inochengeta zvipembenene zvakapfava zvakakwana kuti ubvume kukwenya kwakakodzera kuti uunganidzwe.
3.PhaMeutic Aid (flavour); Zvibereko zvemichero zvinokwana; solvent ye nitrocellulose, varnish, lacquers, uye ndege dzezvemhepo; Kugadzira yehupfu hwehupfu, hweganda rekunze, mafirimu emifananidzo uye mahwendefa, silika yakasimba, zvinonhuhwirira; kuchenesa zviyero, nezvimwe.
